If your Fortress.TeleCom runs on batteries frequently because the input utility line varies often,
you may want to adjust your Fortress.TeleCom to accept wider voltage variations before switching
to batteries. Appendix A describes how to adjust the Fortress.TeleCom from the front panel in
response to specific utility power problems. You should have an electrician check your nominal
line voltage and determine if the problem is due to a "Surge" (high) voltage or "Brownout" (low)
voltage. Changing the setting without this knowledge could make the problem worse.
To silence an alarm, press the alarm silence button on the front panel. The beep will stop, but the
alarm light will stay on. Note: Silencing the alarm does not solve the problem that caused it. See
Tables 2 and 3.
Table 2: Audible Beeps
Number of Beeps
1 every 10 seconds
2 every 10 seconds
3 every 10 seconds
3 every 5 minutes
1 beep every second
Continuous
Steady: Acceptable input power is present. The unit is
running on line power.
Off: No input power is present or the unit is switched off.
Blinking: The unit is boosting or bucking utility power.
Boost = Automatically increases low input power to prevent
the unit from switching to battery.
Buck = Automatically decreases high input power to prevent
the unit from switching to battery.
The unit is running on battery power.
Output Overload: Refer to Tables 2 and 3.
Replace the Battery or UPS Fault. Refer to Tables 2 and 3.
Line Loss: The unit is on battery power. See Table 3 for more information.
Low Battery Alarm: The unit was running on battery power and shut down due
to very low battery voltage. The unit will restart automatically when acceptable
power returns.
Replace the Battery: The battery needs to be replaced. See "Replacing the
Batteries."
Battery Undercharged: While on line operation, low battery voltage indicates
that the battery will provide minimal backup time.
Output Overload: Too much load equipment.
1) Output Short Circuit
2) Starting Fault: Input voltage out of range when unit is turned on.
3) UPS Fault: UPS internal failure.
